FREDERICK HEYL, OF IRVINGTON, NEW JERSEY.

CHAMBER-PAIL.

SPECIFICATION forming part of Letters Patent No. 250,243, dated November 29, 1881.

I Application filed October 1, 1881. (No model.)

To all whom, it may concern.-

Be it known that I, FREDERICK HEYL, a resident of Irvington, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Chamber- Pails; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it a'ppertains to make and use the same, reference being had to the accompanyin g drawings, and to letters of reference marked thereon, which form a part of this specification.

This invention relates more especially to that class of chamber-pails adapted to perform the double service of acting in the usual capacity of chamber-pails and as a seat upon which to stool, the object being to prevent the escape of disagreeable odor from the same, as will be set forth.

The invention consists in the arrangement and combination of parts, all substantially as will be hereinafter fully set forth, and embodied in the claims.

Referring to the accompanying drawings, in which similar letters of reference indicate like parts in each of several figures, Figure 1 is a side elevation of a pail, partially in section, to show the internal arrangement of parts, and Fig.2 is a plan of the under side of the cover, showing more clearly the operation of certain mechanism for securing the lid of the pail upon the body.

In carrying out my invention I construct the body of the pail A in the usual manner, the upper or seat portion, a, being rounded, as shown in sectional portion of Fig.1, to give comfort to the person seated thereon. From the inner rim 1) of the seat the inner wall of the pail tapers, or is beveled downwardly and outwardly, as shown, for a purpose hereinafter made evident.

The pail being formed, 1 construct the lid or cover substantially as follows: Between an upper plate, d, and saucer-shaped under plate, 0, I secure, upon a spindle,f, a disk, g, which is adapted to revolve with said disk when act-uated by the lid-handle h. Connected with said disk are arms 2', which are loosely riveted at regular distances upon the face of said disk, and project therefrom obliquely, or in a manner approaching a tangential direction, passin g, or being adapted to pass, through perforations in the side wall of said saucer-shaped under plate. When the handle h, spindlef, and disk 9 are turned, and the tangential direction of the arms approaches a radial, as will be understood, the arms 5, which work loosely upon the disk, will be projected through the perforations, and will pass under the rim of the pail, holding the cover securely thereon. The inner edges of the perforations are pro vided with guards it, which hold the outer extremity of the arms i in position, and prevent them from becoming disarranged when they are drawn back, and the disk 9 is provided with a stop-lug, l, which limits the distance of revolution ofthe same by engaging with the guards it when the arms are drawn in. The armsi striking against the guard and under plate, 0, limits the action of the plate in the opposite movement, all of which will be seen and understood upon reference to Fig. 2.

Between the upper plate and the edge of the under plate is secured a rubber washer or packing, m, which projects beyond the under plate, as shown, so that when the cover is in position upon the pail said washer or packing will lie between the upper plate, d, and the seat portion a of said pail A, and when the arms are projected in the manner hereiuhefore set forth power will be brought to bear upon the upper plate to form, with said rubber, an airtightjoint, all as will be evinced by reference to the drawings. The projecting arms '5 engaging with the inclined walls of the pail produces the power above mentioned.

The device thus arranged and operating prevents any escape of disagreeable effluvia, as will be understood.

Having thus described my invention, what I claim, and wish to secure by Letters Patent, 1s-

1. The combination, with a chamber-pail, of a cover having an upper and lower plate with a rubber washer secured between them, a spindle and disk connected with a handle and secured between said plates, and arms working on said disk, adapted to engage with the rim of said pail to hold the cover thereon, all substantially as set forth and shown.

2. The eombination,with the upper and lower plates having packing between, of the disk whole being arranged and combined substanworking on a spindle in said plates, having tially as and for the purposes set forth and the arms and stop-lug thereon, all arranged and shown. I 5

operating substantially as and for the purposes In testimony that I claim the foregoing I 5 set forth and shown. have hereunto set my hand this 13th day of 3. In a chamber-pail cover, the upper plate, September, 1881. d, adapted to lie upon the top of the pail, the I lower platehavin g perforated side walls, adapt- FREDERICK HE ed to pass into the mouth of the pail, and the Witnesses:

1o arms connected with a spindle passing through CHARLES WINTERS, said perforated plate, and adapted to engage OLIVER DRAKE, with the under side of the rim of the pail, the GEO. S. FRANCISCO.
